Browning 1042548 Qd V Belt Sheave 1 Groove 6.95 in Od

Product Description

The BROWNING 1042548 is a quick-detachable (QD) bushed V-belt sheave designed for single-groove power transmission applications in HVAC, industrial fan, and blower drive systems. Built from cast iron, this sheave accepts an H-style QD bushing and accommodates bore diameters from 3/8 inch up to 1-1/2 inches, giving installers flexibility across a range of shaft sizes. The outside diameter measures 6.95 inches, with a belt pitch A diameter of 6.2 inches and a belt pitch B diameter of 6.6 inches. At 3.25 pounds, it is a solid, production-grade component suited for licensed HVAC technicians and mechanical contractors.

This sheave is used in single-groove V-belt drive configurations on equipment such as belt-driven air handlers, supply and exhaust fans, and centrifugal blowers found in both residential and light commercial HVAC installations. It is compatible with A-section and B-section V-belts. The QD bushing system allows for straightforward shaft mounting and removal without requiring specialized pullers in most applications, making it a practical choice for field service and replacement work.

Installation Notes

Installation and replacement should be performed by a qualified HVAC technician or mechanical contractor with the drive system fully de-energized and locked out per OSHA lockout/tagout procedures. The H-style QD bushing must be sourced separately and installed to manufacturer torque specifications for the bushing series. Verify belt section, sheave alignment, and belt tension after installation before returning the system to service. Do not operate the drive without all guards in place per applicable mechanical codes.
